Process completion not listened anymore

[ciche...@fater.it]

I created a project named "Delegation Workflow" with a delegation list process started via a Web Interface.

It was working until few weeks ago but now it seems like "ApiListener" does not "catch" the end of the process, thus the Web Interface does not show the result on the screen.

The process report shows that the process ended regularly and it filled fine the array to be displayed.

Could you, please, help on this ?

Thank you,
Luigi
